Jeez. The singer hasn't even had a full week to deal with her split from rapper G-Eazy and already the rumor mill has grown heavy with inklings she's already moved on with another musician, fellow emcee MGK specifically.

Such rumors an insider of hers was quick to quash, telling Us Weekly exclusively, “Halsey and Machine Gun Kelly are just friends. She definitely isn’t rebounding with him."

Whispers of Halsey's rebound romance with the "Bad Things" star began circulating after the duo was pictured sharing a smoke together outside Poppy nightclub in West Hollywood last week (June 28).

Though, as the source explained it, their friendship is purely platonic: "They have known each other for a long time and share a ton of mutual friends.”

The "Him & I" collaborators-slash-lovebirds-before lasted all of one year before the vocalist announced via Instagram that she and G-Eazy were going on an extended break.

"I normally keep this kind of thing private but provided our public nature I feel I need to inform my fans," she wrote of the breakup in an Instagram Story. "G-Eazy and I are taking some apart. I'm eager to continue the upcoming passage of time dedicating myself to my art and career, and the duration of my tour. I wish him the best. Thanks for respecting our privacy at this time."

Although she's yet to confirm anything, guessing by the nature of her Instagram account — which has since been purged of all-things G-Eazy — those cheating suspicions may not have been that far off after all.
